+`morph get-repo` can be used to just clone and checkout a repository,
+without changing the morphologies in definitions.
+
+    SCENARIO morph get-repo checks out a repository
+    GIVEN    a workspace
+    AND      a git server
+    WHEN     the user creates a system branch called foo
+    AND      the user gets the repo for chunk test-chunk in branch foo
+    THEN     morph succeeded
+    AND      the repo for chunk test-chunk was cloned into the system branch foo
+
+We can also specify the directory to clone the repo into.
+
+    WHEN     the user gets the repo for chunk test-chunk from branch foo in directory foo
+    THEN     morph succeeded
+    AND      the repo for chunk test-chunk was cloned into the directory foo
+
+A ref to checkout can also be specified.
+
+    WHEN     the user gets the repo for chunk test-chunk from branch foo in directory bar at ref master
+    THEN     morph succeeded
+    AND      the repo for chunk test-chunk was cloned into the directory bar
+    AND      the repo in directory bar has HEAD master
+
+This should not work if the directory already exists.

+    WHEN     the user attempts to get the repo for chunk test-chunk from branch foo in directory foo
+    THEN     morph failed

 To produce buildable morphologies, we need them to be of the same
 architecture as the machine doing the testing. This uses `morph
 print-architecture` to get a value appropriate for morph.
